Having been individually tested on a large amount of branded swithes and servers, FS transceivers break free of vendor lock-in and guarrantee continued flawless interoperability and compatibility with third party vendors as blow.

Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, FS.COM strongly recommends cleaning both connectors each time you disconnect and reconnect them. FS.COM High Quality One-Push Fiber Optic Pen Cleaner for 1.25mm LC/MU Connector is the best cleaning choice for 10G CWDM SFP+ transceivers. By FS on 08/10/2017

FS.COM has been maintaining adequate stock level of the CWDM SFP+ transceivers in U.S. warehouse, EU warehouse and CN warehouse. As long as the products you order are all in stock, we will ship them out the same day you place your order. As for some specific products or products that have a short stock, we will keep you informed ahead of time before you place your order. By FS on 07/08/2017

Besides the price advantage we have compared to branded transceivers, FS.COM compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.

The AM helped me to check whether the modules were compatible with Cisco Nexus 3000 switches. After receiving the affirmative answer, we bought two. Plugged them on the switches, the LED turned on, and zero packets dropped.

We worked in Philadelphia. I'm grateful that FS has a warehouse in Delaware, and the AM shipped the CWDM modules from the warehouse. They arrived without any damages. We did a test on our switch, the modules worked as advertised.

We have a Cisco C9500-24Y4C switch, and we were searching for the Cisco compatible transceivers with wavelengths of 1550 and 1570 for 8G fiber channel transmission. These modules should be installed in CWDM MUX. We were not sure if this 10G CWDM module works or not so I checked with the AM and the FS technical group gave me advice. I bought these modules on the recommendation. This works very well, and I’ d like to say it is just the solution I needed.

We had two CWDM devices with 1470nm and 1490nm, the two CWDM mux demux were single fiber. We needed a pair of 10G CWDM modules. So we asked FS for advice. My account manager gave me really useful recommendations. We picked this CWDM module and confirmed it is the right device that we needed. These modules did a very good job, without any issues. I would buy more from FS if I need.

I bought these 1470nm 40km transceiver modules to use in Cisco Nexus 3172 so as to connect the CWDM MUX and they just worked exactly as expected. Instantly recognized and run at 10Gbps as soon as I plugged it in. They are priced very well and even have a 5-year warranty. I am super satisfied with the price and value of FS product.

I purchased 12 pcs of these CWDM SFP+, but the channels are chosen wrongly. So I contacted my Account Manager and got very quick response. The replacements were shipped out soon! Great after sales service!

I really want to use FS products for our future projects. I placed this order just for testing. We received these CWDM SFP+ 40km optics and tested them on our switches today. They are working just fine! Also, these optics look decent. Compared to the original one, the price of FS products are reasonable. I’ll surely start placing orders at FS.COM.

We have a new project, the link distance is 66km. I just want to order some transceivers from FS.COM. Suprisingly, their engineers helped to design a free solution for me. I was satisfied with the solution, so I ordered some mux/demux and other accessories from them finally.
